  • Publication number: 20080303018
    Abstract: Due to the indirect transition characteristic of silicon semiconductors, the light extraction efficiency of a silicon-based light emitting diode is lower than that of a compound semiconductor-based light emitting diode. For this reason, there are difficulties in practically using and commercializing silicon-based light emitting diodes developed so far.

  • Publication number: 20080239214
    Abstract: A display device includes a first substrate including pixels and sensing electrodes corresponding with the pixels, and a second substrate facing the first substrate. The second substrate includes an organic layer with a black matrix dividing the pixels and a sensing spacer opposite to the sensing electrode. The organic layer including the black matrix and the sensing spacer may be formed in a single process using organic photoresist material. A mask includes a light-intercepting pattern including slits to block a portion of ultraviolet light emitted towards a photoresist layer to form the black matrix. The mask also includes a pattern to block ultraviolet light in a region corresponding to the sensing spacer if a negative type photoresist material is used, or the mask does not block ultraviolet light in the region corresponding to the sensing spacer if a positive type photoresist material is used.

  • Publication number: 20070257896
    Abstract: An apparatus and method for inputting a character using a keyboard displayed on a touch screen in a portable terminal. The apparatus and method determines if a touch signal is generated, with the keyboard displayed. Upon generation of the touch signal, a touched character is recognized by analyzing the touch signal. The character is displayed enlarged in a predetermined screen area. It is then determined if the touch has been completed, while the character is displayed enlarged. Upon sensing the touch completion, the character is displayed in a main screen area.

  • Publication number: 20070121054
    Abstract: A display substrate includes a transparent plate and a liquid crystal dispersion adjuster. The display substrate includes a display area and a peripheral area surrounding the display area. The liquid crystal dispersion adjuster is formed in the peripheral area to modify the movement of the liquid crystal. The dispersion adjuster includes enhancing parts and a suppression part. The enhancing parts increase the dispersion of the liquid crystal, and the suppression part reduces the dispersion of the liquid crystal, thereby reducing non-filling area of the liquid crystal and the contamination of a seal-line.
